Comparison of Different Solid-Phase Cleanup Methods Prior to the Detection of Ciguatoxins in Fish by Cell-Based Assay and LC-MS/MS.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ciguatera poisoning (CP) is the most reported food poisoning associated with fish consumption. Ciguatoxins (CTXs) are produced by microalgae and metabolized in fish; even low levels of these toxins in fish can lead to CP. To date, there is no unique validated methodology for their study, and demonstrating their presence in fish tissues is an analytical challenge. The main techniques used are cell-based assay and liquid chromatography, which may present different matrix effect interferences; thus, purification protocols are necessary. Six cleanup strategies for fish extracts, assessing the principal analogues found in fish in different parts of the world (CTX1B/CTX3C/C-CTX1), are compared here. Cleaned-up extracts are evaluated by cell-based assay and chromatography. All protocols are suitable for recovering the analogues of CTXs. Two of them, those that used polystyrene-divinylbenzene and silica cartridges, achieve the most adequate results showing toxicity in their fractions over 53% and chromatography efficiencies over 79% for CTX1B/CTX3C, proving to be the most versatile clean-ups for the study of the different CTX analogues.
